[Addon] Jamba - An assistant for multiboxers. Patch 5.0.4 Beta Testing. BETA #3 released.

[Iru]

Jafula: UnitIsGroupLeader is being called incorrectly throughout Jamba/JambaTeam.lua in beta available on Curse. You're using

UnitIsGroupLeader() == 1

Correct invocation is

UnitisGroupLeader("player")

and the function returns true/false

Separately, I can't tell from the OP whether that's you have tested or you need tested. If you could mark that up somehow, I could test the things you haven't got to yet.
